The hybrid qualitative ERA approach is recommended in the above situations with the exception of instances where local regulatory agencies require a different approach. The hybrid qualitative ERA approach estimates erosion risk by dividing a site into areas based on soil, slope, and ground cover, then rating each area as low, moderate, or high erosion risk (link erosion potential subsection) to help choose the right erosion control practices for each stage of construction.
